I'm so stupid. I have a chance to get promoted. But I gave the opportunity to someone else. I won't do it. It's so annoying that I don't know what to do.

Do you think you really have the ability to do this job well after your promotion? It's not because you are stupid, but because you haven't practiced enough. Grasping opportunities is also an ability. You should see clearly the direction of the opportunity and make good use of it. I won't do it. This is just an escape. Avoid the failure that you can't bear, attribute the reason to yourself and give the opportunity to others. If there is an opportunity, even if you let it go, you can't let it go. What you have to do now is to take care of yourself and hone yourself. Look at the development of things.
